EDITOR'S NOTE 

Please note that my correct zip code is 90814 NOT 94501 as indicated on the last 
two issues. 

Thanks to all of you for your patience and continued support. Thanks especially 
to Don Cadien, James Lance, Tom Cockburn, Sandra Millen, Hans Bertsch, Jeff Hamann, 
Eveline Marcus, Clayton Carlson, Bob Burn, I.S. Roginskaya, and Dave Behrens, who 
have recently sent information for the newsletter. 

PERSONAL NOTES 

From Jeff Hamann: "I made an interesting trip to Cedros Is. in August. ^My wife, 
parents, 3 brothers and 1 year old daughter spent a week aboard a friend's boat, the 
Kalinga. We dove the southern end of trie island and found 13 species of nudibranchs. 
The two worth mentioning were a new chromodorid and a range extension for an 
unnamed coryphelid. I brought the chromodorid home and Jim Lance is working it 
over. We also found a new species which I've sent to Dave Behrens. The other 
species are more what you'd expect: Chromodoris macfarlandi, Dendronotus frondosus, 
Doto kya, D. amyra, Eubranchus rustyus, Facelina stearnsi, Flabellinopsis iodinea, 
Polycera atra, Hypselodoris californiensis & Cadlina flavomaculata. 

Grace & Tom Cockburn had their first child, a boy, Brian Andrew, on December 27, 
1980. Congratulations! 

Dr. S.A. Mileikowsky died suddenly on September 12, 1980. His works included 
seasonal dynamics of pelagic larvae of bottom invertebrates, and particularly 
breeding and larval distribution of Pteropoda. 

Bob Burn identified the dorid on Carlson & Hoff 's Christmas card as Chromodoris 
bullockl Collingwood, 1881 which has also been found in Northern Australia. 

From Hillary H. West: "I am currently an assistant professor of biology at Illinois 
State Uniiversity. In 1980 I received my Ph.D. from Northeastern University, Boston, 
MA. My thesis work was an investigation of chloroplast symbiosis and development of 
Elysia chlorotica a local salt marsh ascoglossan. Currently Dr. June Harrigan (of 
the NITT Biophysics program at Woods Hole) and I are collaborating on a study of the 
inheritance of variable reproductive modes in this animal using laboratory crosses." 

Dr. Itaru Usuki is now working in the field of Protozoology and is not doing any 
opisthobranch research. 

From Jeff Hamann: "I've finally finished sorting slides from Aruba. I also used 
Jim's [Lance] great library to identify most of them. 1 had all three of my brothers 
collecting with me & we came up with a grand total of 22 species. Snorkelling proved 
to be most productive as there is little or no tidal throw & only 3 specimens were 
collected in over 10' of water. Elysia cauze, Elysia ornata, Oxynoe antillarum, 
Aplysia dactylomela, Berthellina quadridens, Pleurobranchus areolatus, Aglaja 
evelinae, Aphelodoris antillensis, Chromodoris clenchi, Hypselodoris ruthae, 
Dendrodoris krebsi, Platydoris augustipes?, Siraius kyolis, Hexabranchus morsomus, 



OPISTHOBRANCH NEWSLETTER Volume 13, Number 2, Page 10 

Phidiana lynceus, Tridachia crispata, Orange porostome, ?Peltodoris brown, Brown 
dorid, Brown & white speckled dorid, Black & white facelinid, ringed aeolid. 

Of interest: Vol. 13 has Chromodoris neona on the front. I have a great range of 
variations from neona to clenchi & beyond. Probably the same species. Marcus only 
has one record of Silraius kyolis - the brown & white speckled dorid has large eggs. 
Direct development? The Facelinidae were found in pairs (3), 1 black & 1 grey each 
time. Sexual differentiation? Platydoris augustipes 130mm?" 

CURRENT EVENTS 

The Bay Area Malacologists meeting was held on Saturday, February 28, 1981, at the 
Long Marine Laboratory, University of California, Santa Cruz. Sorry I did not 
receive notice for the February issue. 

The 62nd Annual Meeting of The Western Society of Naturalists will be held 
December 27-30, 1981 at the Santa Barbara Museum of Natural History in California. 
One of the symposiia willl be "The Ecology of Marine Gastropods" with Dr. James 
Nybakken of the Moss Landing Marine Laboratories acting as chairman. Deadline for 
abstracts will be October 29, 1981. Later meetings planned include Australia, July 5- 
17, 1982 and Los Angeles, December 27-30, 1982. For further information contact 
David H. Montgomery, Secretary, Department of Biological Sciences, California 
Polytechnic State University, San Luis Obispo, CA 93407 (805) 546-2446. 

READER FORUM 

Dave Behrens writes an open letter regarding announcements of synonymy: "Several 
years ago I read an abridged edition of the Rules of the International Committee on 
Zoological Nomenclature. In this document I thought I read of certain standards by 
which nomenclatural processes were to be carried out today. With this in mind, I 
remain confused concerning the apparent ease by which names change by synonymy. By 
this I mean, I was of the understanding that before a name is dropped the 
recommending author is to give some explanation for the nomenclatural change. I 
hardly know where to begin to provide examples of exceptions to this practice, and 
those given here are in no way singled out as extreme examples, but rather are 
recent. 

ICZN nomenclatural rules specify that such changes must be published in a 
permanent, publicly available record obtainable by purchase or free distribution. I 
thought the intention of this statement was that such nomenclatural changes be 
consumated in scientific journals, not in privately published editions and handbooks. 
Keen (1971) and Kay ( 1 980 ) have been criticized openly for describing new species of 
molluscs in expensive, limited distribution book editions. Cadien (1980) set two 
opisthobranch synonymys by simple statements of such. Farmer (1980) and McDonald & 
Nybakken (1980, released in 1981) follow several synonymys proposed in formal 
journal publications. These synonymys were proposed without evaluation of the 
genera worldwide, and without the evaluation of the species cited by the above 
authors. To be more specific, Thompson (1975) synonymised Anisodoris and Diaulula 
with Discodorls. He made no reference to A. nobilis or D. sandiegensis of the 
Pacific. McDonald & Nybakken apparently accept this change for Diaulula, but not for 
Anisodoris, why? They give no explanation for either. Miller (1974) synonymised 
Facelina, Hermissenda and Emarcusia with Phidiana. Again the author of the synonym 
made no reference to the northeastern species: F. stearnsi, E. morroensis and P. 
pugnax. In an acknowledgement of H. crassieornis, Miller states 'One type of tooth 
which perhaps shows sufficient differences for use in generic separation is that of 

Hermissenda crassieornis ' Coryphella sabulicola has been listed as a synonymy 

C. iodinea (Cadien, 1980; McDonald & Nybakken, 1981), no explanation was given for 
dropping this recently described species and one might wonder if either has ever 
seen the animal. McDonald & Nybakken go further, and with no explanation, use 
Atageraa alba (0'Donoghue, 1927) over A. quadrimaculata Collier, 1963; Phidiana hilt< 
(0'Donoghue, 1927) over P. pugnax Lance, 1962; and Triopha occidentalis (Fewkes, 
1889) over T. maculata MacFarland, 1905 (previously T. grandis). In the latter case 
they refer the reader to A.J. Ferreira (1977) for details, even though it was 
Ferreira who carefully reviewed the genus and showed T. grandis to be a junior 
synonymy to T. maculata, and that Cabrilla occidentalis as given by Fewkes (1889) 
does not correspond to any nominal species of Triopha. If changes such as these are 
going to be published, particularly in non-journal manners, then they must give 
explanations for such. 

Is it good science to change a name by simple and short 'All genera listed 
above. ..must be merged, because these similarities far outweigh the differences 
between them.' (Thompson 1975; 487) with no reference to species worldwide, 
particularly when four sentences prior the author states 'The taxonomic confusion 
between the numerous species of Discodorls that have been proposed is incapable of 
solution at present.'? Is it good science to change a name by a simple and short - 

(Synonymy: j with no explanation or discussion? I solicit comments 

on how we can allow such scientific techniques to continue." David W. Behrens. 






From Steven J. Long: I have been including pyramidellids,.l£mellarians, Titlscania, 
and onchidians in the ON since the beginning of volume one. These animals have 
typically been studied along with opisthobranchs and so I have included them in the 






OPISTHOBRANCH NEWSLETTER Volume 13, Number 2, Page 11 

ON. Since, of the four, only pyramid ellid s are even related closely to 
opisthobranchs, I have decided to drop the other three without further ado. 
I would like to hear some comments on the pyramidellids. Are they really 
opisthobranchs or are they something else? The shell collectors certainly seem to 
be the only ones working with them. Here are the groups 1 would include.

From Sandra Millen: "I am, enclosing a drawing done by a friend, Floy Zitton, of 
Okenia vancouverensis (O'Donoghue, 1921). This was drawn from a preserved specimen 
in my collection. I regret to say I have yet to see the living animal, but if it will 
reproduce well enough, I would like you to put it in the O.N. so that people will 
realize that it does exist. Another species which Dave Behrens had under rare or 
questionable animals (pg. 107) and which is in fact very common here is Coryjphella 
fusca. This enormously large (to 14cm) animal is common in the winter on soft 
bottoms where it appears to eat tube worms of the family Chaetopteridae. It has been 
reported as far north as Port Valdez, Alaska (Robilliard, 1974)."

SPECIMENS 

South Australian Marine Specimens, P.O. Box 362, Blackwood 5051, South Australia, 
will collect and ship to you preserved intact specimens of all molluscan species. 
Their 1980 price list gives the price at $3-00 (Australian) for the first specimen, 
each additional $1.00 (Australian). For small species the additional charge may be 
waived depending upon the ease of packaging and preparation. Only one 
opisthobranch appears in their newest list: Bulla tanuissima, however they are willing 
to collect anything you request. Photographs are also available of live animals, at 
80 cents per copy. 

Species collected or observed in the Channel Islands off the California coast. 
Please send names and Island locations to Dave Behrens, 416 Lilac Drive, Los Osos, CA 
93402. Dave is compiling an annotated check-list of branchs of the Channel Islands 
for publication at a later date in the ON. Presently his list numbers only about 30 
species and concentrates solely on Catalina and Santa Cruz Islands. Information on 
the other islands is needed. 

Sandra Millen (The University of British Columbia, Department of Zoology, 2075 
Wesbrook Mall, Vancouver, B.C., Canada, V6T 1W5) would like specimens of Onchidoris - 
any species (except bilamellata) and Adalaria - any species. European as well as 
North American species would be appreciated^

REVIEW 

Two photographic works are listed in this issues from James Lance. The 
quality of the photographic and printing work is unsurpassed by anything 1

From Judith Hunter: "I would like to endorse your 
of common names for animals which do not have them 
given more prominence than the scientific name."

From Dr. Riccardo Cattaneo: "I need some information. Firstly I have 
begun a study of electrophoresis on some nudibranchs (especially eolids) to 
see if there are differences in the enzymes of species who live in the same 
community and feed on the same hydroids. This study may be interesting also 
for systematic problems. I have not found many references about this 
argument. Is it possible to know something more? Would anyone who has any 
news please write to me? 

Secondly, I have seen in Thompson's paper (1975) that gen. Peltodoris 
Bergh 1860 is in synonymy with Discodoris Bergh 1877- I know Peltodoris 
atromaculata Bergh 1880 (type species of the genus), which is very common 
Mediterranean Sea, very well. The description in Thompson's paper for the 
genus Discodoris speaks of a 'whole body flexible, not hard and rubbery'. 
Peltodoris atromaculata has however a very hard body, very rich in spicules 
I think this genus must be conserved only for this very evident 
characteristic which is part of the type species of the genus." 

From Eveline Marcus: "Your question about Pyramidellid s: Vera Fretter and 
Alastair Graham have (1949, J. Mar. Biol. Assoc. U.K., 28:493-532) conciudea 
that they are opisthobranch gastropods. In 1965 Doris Maas (Zeitschrift 
Morphologie una Okologie. 54:566-642) confirms Fretter and Graham. 

On p. 11 of the News Letter you place the Notaspidea (often called 
Pleurobranchomor pha ) in the Nudibranchia . However, a great number of them
